Service Stopping Unexpectedly

ERROR | wrapper | 2007/05/18 14:32:07 | JVM appears hung: Timed out waiting for signal from JVM.
ERROR | wrapper | 2007/05/18 14:32:07 | JVM did not exit on request, terminated

Thoughts?

Version is 3.0, been pretty stable for a while, but this happened twice in the last few hours. :(
